Purpose: The present study was conducted to the derive sensory terms of seven spicy sauce samples for Korean and Vietnamese people, and define flavor characteristics and other sensory characteristics for each sample. Methods: Total of 9 Korean and 10 Vietnamese panelists were selected. Each group was trained, and to identify the product attributes, descriptive analysis were performed independently. Results: The descriptive analysis revealed that a total of 34 terms were derived for Korean people, showing significant differences in all attributes(p<0.05) similar to 33 terms for the Vietnamese, but with significant differences in 32 items, excluding the fiber characteristics of appearance(p<0.05). For both Korean and Vietnamese, the characteristics of “sweet flavor” could be affirmed to act as a factor moderating the characteristics of spicy flavor. In the case of the Korean people, the attributes of “burning sensation” and “acridity” were affirmed to be the texture characteristics related to nonvolatile spicy flavor, while the characteristic “spicy flavor” was recognized differently in terms of both flavor and mouth-feel in the case of the Vietnamese people. Conclusion: The results of this study show that Koreans do not use the word ‘spicy taste’ and other ‘spicy sensation (burning sensation and acridity etc.)’ separately, while the Vietnamese use the same word ‘spicytaste’ as well.

야채가 혼입된 들깨죽 제조의 시뮬레이션 연구로 볶은 들깨와 쌀, 물의 혼합물의 가열 중 클로로필(0.33 mg/kg)과 베타-카로텐(3.3, 9.9, 19.8 mg/kg)의 첨가에 의한 지방질의 산화와 토코페롤의 변화를 모니터링하였다. 시료의 가열과정 중 과산화물값과 공액이중산값이 증가하여 들깨죽 지방질의 산화가 발생하였음을 뚜렷이 보여주었으며 클로로필과는 달리 베타-카로텐은 농도의존적으로 지방질의 과산화물값과 공액이중산값을 감소시켰다. 들깨와 쌀, 물의 혼합물에 첨가한 클로로필과 베타-카로텐 및 시료에 함유되어 있던 토코페롤의 분해는 가열 시간에 대해 1차반응이었으며 베타-카로텐은 가열 과정 중 토코페롤의 분해를 억제하였다. The effects of chlorophyll (0.33 mg/kg) and β-carotene (3.3, 9.9, 19.8 mg/kg) addition to a mixture of roasted perilla seeds, rice, and water (30:45:225, w/w/w) on the lipid oxidation and tocopherol contents were studied during heating at 100℃ for 120 min to simulate cooking of perilla and rice porridge. Lipid oxidation was evaluated with peroxide values (POV) and conjugated dienoic acid (CDA) values, and chlorophyll, β-carotene, and tocopherols were determined by HPLC, POV, and CDA values were increased during heating, indicating the occurrence of lipid oxidation in the perilla and rice porridge. β-Carotene decreased the POV and CDA values of the samples in a concentration-dependent manner, while the addition of chlorophyll did not affect them. Chlorophyll and β-carotene which were added, and tocopherols naturally present in samples were degraded, following the first order kinetics during heating, and β-carotene protected tocopherols from degradation.

The purpose of this study was to analyze the key factors considered important by customers in the selection of a Korean restaurant through the use of conjoint analysis techniques. A total of 400 questionnaires were distributed over a 2-week period in October 2011, of which 354 were completed (88.5%). Statistical analysis was then carried out using the Windows 18.0 Statistics package. The research was based on the analysis of two target areas - daily meals and special purpose meals. Responses were measured by using Zaichkowsky's Personal Involvement Inventory (PII) and a 7-point Likert Scale. Overall it was found that in all areas of the results regarding the involvement related analyses, daily meals scored lower than special purpose meals. This implied that the choice of daily meals is more applicable to customers with a low level of involvement, whereas high-involvement customers were more likely to focus on special purpose meals. The analysis of high-involvement customers revealed that the quality of food, price, service quality and physical environment, in order of priority, were the most important factors in selecting a restaurant. The use of the optimum attribute combination revealed the following results: delicious food (0.601); friendly staff (0.170); clean restaurant (0.191); price of 20,000 won (-0.513). Furthermore, low-involvement customers considered the following factors as important when selecting a Korean restaurant: quality of food, followed by price, physical environment and service quality in that order. In this instance, the optimum attribute combination showed the following outcomes: tasty food (0.645); friendly staff (0.418); clean restaurant (0.365); price of 5,000 won (-0.847). These results indicated the importance of developing a marketing plan which was based specifically on a customer's involvement level, focusing on their main selection criteria when choosing a Korean restaurant.

This study examined the quality characteristics of Jeung-pyeon made with wet non-glutinous rice flour and rice wine. The samples of Jeung-pyeon were prepared with different ratios of cooked purple sweet potato (0, 3, 6, 9, and 12%) to analyze the water content, sugar content, pH, chromaticity, texture characteristics, and sensory evaluation. No significant difference in water content, sugar content, and springiness was observed among the 5 samples. The pH and volume showed the highest level at 0%. The L-value and b-value decreased while the a-value increased. The hardness, chewiness, and gumminess were highest at 9% and lowest at 12%. The extent of violet chromaticity and pore size were optimal in 9%. In addition, 9%-added purple sweet potato showed the highest score of odor, taste, texture, and overall acceptability. In conclusion, the optimal addition for the highest acceptability of cooked purple sweet potato was 9%.

Purpose: This study investigated beef restaurant's selection attributes using conjoint analysis in order to provide useful information to marketers and managers. Methods: A total of 320 questionnaires were distributed to consumers who visited a beef restaurant in August 2016, and 284 were completed (96.90%). Statistical analyses of data were performed using SPSS/Windows 22.0 for descriptive statistics and conjoint analysis. Results: The results of this study demonstrate the relative importance and level of each attribute for selecting beef restaurants. Price showed the greatest importance (34.86%), followed by origin of beef (27.52%), level of support services (25.72%), and variety of side dishes (11.90%). The optimum attribute combination was various side dishes (0.059), Korean beef (0.385), Very high service level (-0.291), and price of 8,000 won (-0.782). The most preferred beef restaurant gained 37.60% potential market share from choice simulation. There were significant differences in importance of attributes related to age of respondents. For respondents in their 20s and older than 50s, the first consideration was price. Respondents in their 30s considered the level of support services first while those in their 40s considered origin of beef first. Importance of attributes based on companion of respondents revealed that all respondents considered price first. Conclusion: This study contributes to development of marketing plans based on a customer's involvement level focusing on their primary selection criteria when choosing a beef restaurant. Additionally, marketers who manage beef restaurants can estimate the market share of imaginary beef restaurants from these results.

연근, 김, 깻잎 부각의 산화방지 활성, 폴리페놀 화합물과 토코페롤 함량

정이진,송영옥,정라나,최은옥,Jung, Leejin,Song, Yeongok,Chung, Lana,Choe, Eunok 한국식품조리과학회 2014 한국식품조리과학회지 Vol.30 No.6

찹쌀풀과 생참기름을 이용한 전통적인 방법으로 제조한 연근, 김, 깻잎 부각의 산화방지활성과 산화방지 성분을 평가하였다. 깻잎 부각이 가장 높은 라디칼 소거 활성과 환원력을 보였으며 연근 부각의 활성이 가장 낮았는데 부각 원료인 데친 연근, 김, 깻잎의 활성과 동일한 순서이었다. 폴리페놀 화합물 함량은 연근, 김 부각보다는 깻잎 부각에서 더 높았고, 부각의 토코페롤은 대부분 튀김유인 참기름에서 유래하였다. 부각의 산화 방지 활성은 폴리페놀 화합물 함량과 높은 상관관계를 보였으나 토코페롤 함량과의 상관관계는 매우 낮아 폴리페놀 화합물이 부각의 산화 방지 활성에 더욱 긴밀하게 기여하고 있음을 의미하였다. In vitro antioxidative activities and antioxidants of the lotus root, dried laver, and perilla leaf bugak, Korean traditional fried cuisine, were evaluated. The bugak was prepared with fermented glutinous rice batter and unroasted sesame oil for use in the pan-frying. The perilla leaf bugak showed the highest radical scavenging activity and reducing power, with the lowest in the lotus root bugak. The antioxidative activity of the blanched lotus root was lower than the dried laver or the perilla leaf. Polyphenol content was higher in the perilla leaf bugak than the lotus root or the dried laver bugak, and tocopherols were mainly derived from frying oil. The antioxidative activity of bugak was correlated well with polyphenol contents, but there was no correlation between tocopherol contents and the antioxidative activity.
